  By the way, the card connector as described above is expected to be miniaturized in order to be mounted on a small electronic device such as a cellular phone. When the card connector is miniaturized in this way, it is necessary to reduce the width dimension of the contacts in order to maintain insulation between adjacent contacts.

  However, when the width dimension of the contact is reduced, the strength and elastic force of the contact are lowered. For this reason, it is difficult to ensure a predetermined contact pressure with respect to the contact portion of the contact card. Further, the contact may be plastically deformed by repeatedly inserting and removing the card.

  The present invention has been made in view of the above circumstances, and the object of the present invention is to reduce the width of the contact while ensuring a predetermined contact pressure of the contact and to improve the plasticity of the contact. An object of the present invention is to provide a card connector that can suppress deformation.

  In order to solve the above-described problems, a card connector according to the present invention includes a body provided with a card insertion hole into which a card can be inserted, a card insertion hole that is movably arranged in the card insertion hole of the body, and is vertically movable. A floating member pushed downward by a card inserted into the insertion hole, a first contact having first and second ends in the length direction, and a bias that biases the lower surface of the floating member upward. Means. At least a part of the first end of the first contact is fixed to the body, and the second end of the first contact is fixed to the floating member, and the second end of the first contact is fixed to the body. A part protrudes from the upper surface of the floating member so as to be able to contact the contact portion of the card.

  In the case of such a card connector, the second end of the first contact is fixed to the floating member, and the floating member is urged by the urging means, so that the first force is applied by the urging force of the urging means. The elastic force of the contact can be reinforced. Therefore, the width dimension of the first contact can be reduced while ensuring a predetermined contact pressure with respect to the contact portion of the card of the first contact. Further, when the card is inserted into and removed from the card insertion hole of the body and the contact portion of the card contacts a part of the second end portion of the first contact, the load applied to the first contact is a floating member. Since the first contact is dispersed by the biasing means, it is possible to prevent the first contact from being plastically deformed even if the width of the first contact is reduced.

  A guide hole communicating with the card insertion hole can be provided in the bottom plate portion of the body. The lower end of the floating member is guided in the guide hole so as to be movable up and down, and the upper end is disposed in the card insertion hole. In this case, since the lower end portion of the floating member is guided by the guide hole so as to freely move up and down, when the floating member is pushed down by the card, the floating member moves in the width direction of the card, and the first contact It is possible to prevent the occurrence of problems such as the part of the second end portion not contacting the contact portion of the card.

  When a fitting hole communicating with the guide hole is provided in the bottom plate portion of the body, the body is fitted into the fitting hole and at least a part of the first end portion of the first contact Has a fitting block to which is fixed. In this case, at least a part of the first end of the first contact is fixed to the fitting block, and the second end is fixed to the floating member. The floating member and the first contact can be easily attached to the body simply by inserting the floating member into the guide hole of the body.

  The card connector may further include a cylindrical cover that covers the outer peripheral surface of the body. The cover has an elastic piece provided on a bottom plate portion thereof, and the elastic piece is inserted from below into the guide hole of the body and functions as the urging means for urging the floating member upward. It is supposed to be.

  In the case of such a card connector, since the elastic piece that is a part of the cover is used as the biasing means, the number of parts can be reduced and the cost can be reduced as compared with the case where the biasing means is provided separately. Can be achieved.

  A notch for opening the guide hole to the rear in the card insertion direction can be provided in the bottom plate of the body. The elastic piece is inserted into the guide hole through the notch. In this case, when the cover is attached to the body, the elastic piece can be disposed below the floating member simply by inserting the elastic piece into the guide hole through the notch. Therefore, the attachment of the elastic piece becomes very simple.

  The card connector may further include a second contact having a length dimension different from that of the first contact. The second contact has first and second ends in the length direction. The first end of the second contact is fixed to the body, the second end of the second contact is fixed to the floating member, and a part of the second end is the floating member. It protrudes from the top surface of. Alternatively, the first end of the second contact can be fixed to the fitting block of the body.

  When the contact portion is formed on the bottom surface of the recess provided at the lower end of the card, it is preferable that the floating member can be inserted into the recess. In this case, when the card is inserted into the card insertion hole of the body, the floating member is inserted into the recess to guide the card. For this reason, it becomes easy to insert the card into the card insertion hole.
